T-type extension rod

Abstract

A T-type extension rod comprises an axle seat provided with two pivot ears, one group connecting axle passing through the pivot ears, a heteromorphism rod handle intersecting with and passing through the group connecting axle, and a cliping fixing unit. The group connecting axle comprises an outer surface, an inner surface which runs through the outer surface in the radial direction and defines a heteromorphism through hole for the crossing of the heteromorphism, a first sink tank which sinks in the inner surface, and a second sink tank which sinks in the outer surface and is corresponding to one of the the pivot ears. The heteromorphism rod handle comprises two reversed cliping fixing end part which has a ring slot. The cliping fixing unit comprises two compression springs which are arranged in the first sink tank and the second sink tank, and two top caps which are covered the ends of the compression springs and whereby press and abut the outer surface of the heteromorphism rod handle and the corresponding pivot ears. The T-type extension rod can drive the driving end by driving the heteromorphism rod handle to rotate vertically; the rotation requires very small space so that it can be applied in narrow work space.

Description

technical field [0001] The invention relates to a T-shaped connecting rod, in particular to a T-shaped connecting rod which can be used in a narrow environment and can ensure the tightness of assembly of its own components. Background technique [0002] refer to figure 1 and figure 2 , an existing T-shaped connecting rod 1, as disclosed in China Taiwan Invention Patent Publication No. I321081, includes a shaft seat 11 with a driving end 111 and two pivot ears 112, and a shaft seat 11 that is rotatably worn on the pivot. Described pivot ear 112 and has the assembly shaft 12 of a radial through hole 121, a bar handle 13 that passes through this through hole 121 and interlaced with this assembly shaft 12, and utilizes two compression springs 141 to match two The fastening force resisted by the steel ball 142 links the components and prevents the fastening unit 14 from autonomous displacement of the components. In this way, the handle 13 can slide axially relative to the ass...

AI Technical Summary

Problems solved by technology

[0006] refer to image 3 and Figure 4 , in order to make the handle 13 fit into the shaft seat 11 without interfering with the pivot lug 112 when rotating, the distance between the pivot lug 112 must exceed the outer diameter of the C-shaped buckle 15, However, this also causes a gap g between the handle 13 and the pivot ear 112, the handle 13 cannot bear against the pivot ear 112 to disperse the stress when rotating, and it is easy to break when it is used. , the T-joint 1 still has room for improvement
